Product details
Overview
S9KEAZN64AMLHR from NXP Semiconductors is an automotive-qualified Arm® Cortex-M0+ microcontroller with 64 KB flash, 4 KB RAM, and 256 B EEPROM, operating at up to 40 MHz core clock and -40 to 125°C ambient temperature. It integrates dual FlexTimer/PWM modules, 12-bit SAR ADC with Stop-mode operation, two analog comparators with 6-bit DACs, and supports UART, SPI, and I²C interfaces for motor control and body electronics applications.
For engineers reviewing the S9KEAZN64AMLHR datasheet, S9KEAZN64AMLHR pinout, S9KEAZN64AMLHR application, or S9KEAZN64AMLHR equivalent, this page delivers verified electrical specs, thermal behavior in 64-pin LQFP, low-power mode current (135 µA in Stop), SWD debug interface timing, and validated alternative parts for automotive-grade MCU selection.
Technical Context
The S9KEAZN64AMLHR implements a single-cycle 32-bit x 32-bit multiplier and single-cycle I/O port access to enable deterministic real-time control. Its internal clock system combines a factory-trimmed 31.25 kHz IRC for 40 MHz system clock generation, a 1 kHz LPO for low-power wake-up, and configurable oscillator modes supporting 32.768 kHz crystals or 4–20 MHz resonators.
Power management includes three operational modes (Run, Wait, Stop), programmable low-voltage detection with four warning thresholds, and CRC hardware acceleration. The device features a bit manipulation engine (BME) for atomic register access and serial wire debug (SWD) compliant with 20 MHz clock and 10 ns setup/3 ns hold timing.
